You should be able to do this via the form DSL method provided by ActiveAdmin. More details are in the documentation for ActiveAdmin and Formtastic.

Unfortunately, I don't believe ActiveAdmin nicely lets you have a completely different form rendered for new and edit. Using the partial rendering method in the documentation though you could conditionally change the form in the view based on @object.persisted?.

# app/admin/post.rb
ActiveAdmin.register Post do
  form :partial => "form"
end

# app/views/admin/post/_form.html.erb
<%= semantic_form_for [:admin, @post] do |f| %>
  <% if @post.persisted? %>
    Edit Form (Maybe rendered via a partial)
    <%= f.inputs :title, :body %>
    <%= f.buttons :commit %>
  <% else %>
    New Form
  <% end %>
<% end %>
